tools: hv: fix compiler warnings about major/target_fname

This patch fixes the below warnings with new glibc and gcc: hv_vss_daemon.c:100:13: warning: In the GNU C Library, "major" is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan to remove this soon. To use "major", include <sys/sysmacros.h> directly. hv_fcopy_daemon.c:42:2: note: 'snprintf' output between 2 and 1040 bytes into a destination of size 260 Signed-off-by: Dexuan Cui <[email protected]> Cc: Stephen Hemminger <[email protected]> Cc: K. Y. Srinivasan <[email protected]> Signed-off-by: K. Y. Srinivasan <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
